INVESTIGATION OF THE LIPID AND CARBOHYDRATE CONTENTS OF GREWIA TENAX FORSSK. FRUITS & EVALUATION OF HEPATOPROTECTION ACTIVITY
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 5
Abstract
Objective: Grewia tenax Forssk. is represented in Egypt and known for its edible fruits which are nutritionally balanced and rich in iron and calcium. This work was to investigate the Lipid and Carbohydrate Contents of Grewia tenax Forssk. fruits and evaluation of Hepatoprotection activity.Methods: Investigation of carbohydrate contents of Grewia tenax Forssk. fruits were carried out using HPLC. The lipids content of Grewia tenax Forssk. fruits were analyzed by GLC. Also, the hepatoprotective activity on rat hepatocytes monolayer culture was studied.Results: The HPLC analysis of free sugars of Grewia tenax Forssk. fruits revealed the presence of stachyose, sucrose, glucose and fructose. While the HPLC analysis of the polysaccharide hydrolysate from Grewia tenax Forssk. fruits showed the presence of glucuronic acid, glucose, galactose and arabinose.GLC of the unsaponifiable matter of hexane extract of Grewia tenax Forssk. fruits revealed the presence of a mixture of a series of n-alkanes (63%) and a series of sterols (9.9%). A series of hydrocarbons ranging from C10-C26 in addition to cholesterol, campasterol, stigmasterol and β-Sitosterol and six fatty acids among which Linoleic acid (C18:2) was the major one (55.5 %) was identified. Also, the hepatoprotective activity study of the extracts of Grewia tenax Forssk. fruits (80% MeOH extract of defatted powder) and water extract indicated that they exhibited hepatoprotection at (25 μg/ml and 50 μg/ml) and (12.5 μg/ml to 100 μg/ml); respectively.Conclusion: Our study was the first record of carbohydrate and lipid fraction contents of Grewia tenax Forssk. fruits. From the obtained results, the highly nutritive and medicinal values of Grewia tenax Forssk. fruits should be considered. Furthermore, and due to the high hepatoprotection effects of the plant extracts, further investigation and studies should be done to isolate the bioactive compounds. Â
